' -,To' all whoirt'it may concern:

Beit known that I, JOSEPH 'Kiniir, a citizen of the United States, residing at Long- .mont, in the county of Boulder and State of Colorado, have invented certain new and 'i'iseful Improvements iii Picture-Projecting Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

The invention relates to an improvement in picture projecting apparatus, and is pri- .inarily directed. to the combination of a phonograph or'other sound reproducing machine and a picture projecting machine, so that 'the icture exhibition may be directly controlled by and timed in accordance with the reproduction on the phonograph.

"The main object of the present invention is the production of a series or intermittent picture projecting machine in which the o eration of the picture carrying slide or s idesis automatically controlled by the opera.

tioii of the phonograph, with the effect to exhibit the successive pictures in direct and 1 concurrent tin'iing'with the particular characteristics of the rendition b y tliephonograph.

'l lie im'eiition will be described in the folliiiviiig specification, 'll-fUl'QlHO being had particularly to the accoin uinyi Fig. '7 is a View similar to i Figure 1 is a perspective View illustrating my improvement.

Referring particularly to the accoiiipun c invention aoplied to a dull-iron. style of piriug drawings, my improvement is designed j'iriinarily aslan.addition to an ordinary 'stereopticon or other picture projecting machine I. I

'macliiiic other than in the particulars hereinllie detailed structure of the after described is not important so far as the present inventionisconcerned and it is to be understood that I contemplate the use of any picture ro ecting machine desired.

For t efpui-poses of the presentinvention Specification 61 Letters Patent.

. co-extenswe in dimensions with the PICTURE-P/RQJECTING APPARATU Patented March 16, 1909.

the forward or face section of the machine is provided with a supporting frame 2, including a back plate 3 secured to or forming the face section of the machine and depending below the same, a bottom late'4 extending at right an les and forward y from the lower end of the ack-plat'e, and a front or disk receiving plate 5, said plate 5 being practically plate 3 but having a hinged connection at 6 with the forward edge of the bottom plate, so that the front plate can be turned down into approxi mately the same plane as the bottom plate.

The condensing lens 7 of the picture machine is carried by or projects through the backplate 3 While the ob ective lens 8 is carriedby the front plate 5,.said lens being of any usual or preferred type and being so arranged that when the front plate is in elevated or o )erativeposition the respective lenses are a lied to permit the projection upon a screen or the like of a picture disposed between them.

Secured upon the forward face of the front plate 5 at a point below the condensing lens is casing 9, within which is arranged a motor, as a spring motor. 10, which may be of any usual orpreferred'type. The main shaft of the motor projects throu hthe front plate and is provided in rear said plate with a supporting disk 11 fixed to the shaft to be revolved by the motor and carrying adjacent its peripheral edge a series of laterally proj ecting pins 12, for a purpose which will presently appean Arrange upon the forward face of the front plate is a slide plate 13, adapted to project through the lower wall of the casing 9 and engage the main wheel of the. motor, whereby in one position of the slide its function is to brake and thereby stop the motor. The slide is controlled by a handle 14 projecting from the slide near the lower edge of the latter, said handle or rod also serving to secure the back plate in elevated or operativeposition, being adapted for this i purpose to engage a hook or upturned member 15 carried on the forward edge of a member 16 secured to the bottom plate, the front plate 5 being formed with an aperture 17 through which the hook 15 is adapted to pass when the plate 5 is in elevated or operative position. By this construction it will be ap parent that as the brake 13 is moved down' ward to free the motor, the rod 14 will ride into the hook or keeper 15 and thereby secure the front plate in operative ,osition, the reverse movement of the rod f feeing the front plate to permit the same to be swun down u on its'hinged connection with the iottom p ate and at the same time braking the motor against further movement.

For the purposes ofthe present invention the pictures are preferably arranged upon a slide carrier 18 of disk form, the pictures being arranged in seriesadjacent the peripheral edge of the slide. These picturesare, of course, of a character to accord with the particular selection rendered by the phonoraph and are of a size to be properly roected by t'he lens of the picture mac iine when arranged between the same in the usual manner. The disk slide carrier is formed with a central opening to fit over the end of the motor shaft, and with a series of openings 19 to engage the pins 12 on the motor disk 1 1,50 that the disk slide carrier may be secured to the motor disk and revolved directlyby the latter under the influence of the motor.

The present invention is directed more particularly to an accurate and concurrent timing of the picture exhibition. with :the rendition on the honograph, to gain which result it will be obvious that one or more of the pictures in the particular series corresponding to the phonograph rendition will be maintained upon the screen much lon er than the others. For this purpose a regu ar and uniform advance of the successive pictures would be of no value, and means must be provided for arranging the particular pic-' ture in exhibiting position and maintaining it in' such position in accordance solely with the requirements of the phonograph rendition. To accomplish this result I secure upon the rear face of the disk slide carrier a controlling ratchet 20 formed with a series of teeth 21 corresponding in number to the numbr of pictures on the slide carrier and ha ing irregular spacings with relation to er eh other and with the center of the slide carrier, that is one tooth will be spaced farther from the center of the slide carrier and a greater distance from the adjacent tooth than under regular arrangement.

To control the movement of the disk I airand is threaded throughout its length inter- The operating har promediate saidhars. jects beyond one of the end bars 23 and 1s terminally squared at 27, or otherwise formed for the connection. of a second operating bar for cooperation with the frame 21, said dog comprising a metallic section formed at one end with a transverse opening to slid ably engage the rear guide bar 24. and adapted to rest upon the forward guide bar 25. Intermediate the points of contact with the guide bars the dog is formed with a semicylindrical depression 29 in its under surface arranged to engage the threaded portion of the operat ing rod 26, said depression being threaded to cooperate with the threads on the operating rod to insure a longitudinal movement of the dog relative to the frame 21 in the operation of the rod. A spring 30 is terminally connected to the dog and to one of the end bars 23 of the frame 21, said spring tending .to inove the dog in opposition to its movement under the influence of the operating rod and being effective to return the dog to normal position upon its disconnection from the rod. Said guide bar 25 is formed with a longitudinally extending, radially disposed rib 26, and it is pivoted in the end pieces 23 so that when it is rotated the rib or projection 26* acts as a cam to elevate the dog 28 and disengage it from the screw threads of the operating rod 26. Upon the outer end of the rod 25 is a lever or crank handle 25 by ineans of which it may be readily rotated. The foryond thejorward guide bar 25 and is adapted for cooperation with the teeth of the control ling ratchet.

T he operating rod 26 is designed to be actuated by a phonograph or other sound reproducing instrument 32, and to provide for such control I arrange a second operating rod 33 terminally formed to engage the squared end'27 of the operating rod 26. The opposite end of the rod 33 is appropriately formed for frictional or other engagement with a moving part of the phonograph so that. the latter will continuously revolve the operating rod 33 and thereby the operating rod 26. The detailed construction of the connection between the operating rod 33 and the phonograph is inuuaterial so far as the present invention is concerned, and the use of any mechanical construction for this purpose is contemplated.

With the parts constructed and arranged as described, the picture disk in place, the dog nose 31 engaging the initial or first tooth of the controlling ratchet, and the operating rods actuated by the phonograph, the operation of my improved picture exhibiting machino is as follows. As the phonograph continues its reitdition, the operating rod 26 is rotated with the eil'ccl' to feed the dog longitudinally of the guide rods 2% and 25. movement gradually discngages the dog from the initial ratchet tooth of the controlling ratcl'ut and permits the motor to move the picture slide until the second or next adto be later described. A dog 28 is arranged jacont tooth engages the dog. As these Ward or nose end 31 of the dog projects bc-' machmeused teeth are arranged in accordance with the" arrangement of the pictures on the slide,

the engagement of the, dog with the. second tooth arranges the second picture in position to be projected upon the screen. This movement is continueduntil the pictures areex- .hausted or the operation of the phonograph istop ed'.

' handle is released said dog will drop into on it is desired to reset the device the crank handle 25 is operated to lift the cam projection 25, which latter swings the dog upon the guide bar 24 so as to lift its screw threaded portion or half nut out of mesh m'ui the screw threaded operating rod 26, whereupon the spring will return the dog to its starting point and when the crank engagement with said operating rod or screw.

'lttwill be particularly noted that the movement of the operating rod 26 is uniform and 3 continuous, but that the respective teeth of the ratchet are irregularly disposed. .From this arrangement it is at once apparent that some of the pictures'will be. maintained in 25 certain articular pictures on the slide in picture ex iibiting position the exact length of time required by the phonograph rendition.

The pictorial representation indicative of the song or composition being rendered by the phonograph will, therefore, accord exactly with such rendition, the'spacing of the teeth "ofthe controlling" ratchet relative to each "other and to the center of the picture slide insuring such operation.

The particular construction of the pic- ;ture slide 'carrier'or picture carrier is not material to the present invention as I contemplate its construction in any manner best adapted for the] particular picture Fig. 7 of'the drawings 1 have shown the invention applied to a polyopticon or picture projecting machine 1 in which the picturest'o be reproduced are disposed opposite an opening 1 at the rear of the body of the machine. The pictures to be proj'ected are asted or otherwise secured upon the-fron t ace of the disk 18, which latter serves asa carrier for the pictures and as it is rotated brings them successively opposite the opening 1" at the back of the machine. so that the reflecting and'projecting apparatus within thelatter will project the images out of the front of the machine and uponthe screen. In this forlnof the invention-the frame 2 is so disposed that its member 3 is beneath the body of the machine. 1 Having thus described the invention, what s claimed asnew, is
